The NM300TP wear-resistant steel is specifically designed for concrete mixer drums, where its high strength and ultra-thin profile provide a unique advantage in reducing vehicle weight and enhancing drum longevity. Manufactured to withstand the continuous abrasive forces exerted by aggregates, NM300TP is an optimal choice for concrete mixing applications requiring lightweight yet durable materials.
Using NM300TP in place of standard carbon or A36 structural steel provides not only extended wear life but also reduced maintenance costs. In comparison with traditional materials, NM300TP’s thinner yet tougher profile supports a higher abrasion resistance, allowing concrete producers to extend their drum’s service life, reduce overall operational costs, and boost production efficiency. Additionally, its high Brinell hardness rating ensures durability against continuous abrasion, resulting in smoother operations and lower long-term costs.
| Steel Grade | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (A50%) | Brinell Hardness (HBW) | Available Specification (mm) |
| NM300TP | 600~800 (660) | ≥900 (1080) | ≥8 ( 15.9) | ≥270 (302) | 3.0~5.0× 1000~1800 |
•Thin Profile and High Strength: NM300TP can be produced in ultra-thin sheets as fine as 3.0mm, allowing for significant weight reduction. Compared to traditional carbon steel drums, this reduces the mixer’s weight by 30-40%, lowering fuel consumption and increasing payload capacity.
•Enhanced Wear Resistance: NM300TP offers extended durability over standard materials, reducing the need for frequent replacements. Its structure and strength provide three to five times the lifespan of regular carbon and high-strength steel, making it an economical choice for producers facing abrasive wear.
•Optimized Production Efficiency: With widths up to 1800mm, NM300TP reduces the need for additional welding and cutting by over 30%. This streamlined production process lowers overall manufacturing costs by 30% and reduces welding fatigue on the drum body.
Concrete mixers experience significant wear due to constant contact with abrasive materials like gravel and sand under both dry and wet conditions. NM300TP’s enhanced wear resistance ensures a long-lasting performance for various concrete mixing equipment, including:
1. Concrete Mixer Drums: Ideal for the primary shell and internal blades, NM300TP enhances drum durability, providing resistance to wear across the entire mixer life cycle.
2. Stationary Mixers and Transit Mixers: NM300TP can be applied to stationary and mobile mixers, ensuring reliable performance across different mixing conditions and contributing to reduced downtime and maintenance costs.
3. Blade and Fin Components: The internal fins and blades can be made from NM300TP to prevent wear, ensuring efficient mixing and improving concrete consistency.
